Held alongside the full and quarter distances, the Rend Lake Half Marathon returns on Saturday, March 29, 2025, in serene Barren Township, IL—nestled in the heart of 19,000 acre Rend Lake. Since its inception in the early 2020s, the event has grown into a scenic spring road tradition, drawing runners seeking lakefront panoramas and small-town charm.
The half distance begins at 9:30 AM CDT near the Rend Lake dam. Runners traverse a certified USATF course that covers the final 13.1 miles of the full marathon loop, with a blend of paved lake causeways, recreational bike paths, and rolling country roads. Highlights include breathtaking views from South Sandusky Beach, around Lake Hamilton and Lake Benton, and a finish at the scenic North Marcum Beach adjacent to the golf course.
Aid stations stocked with water, Gatorade, gels, and port-a-johns are positioned throughout, and volunteers earn praise for their support and local hospitality. Reviewers say the course is “a marathon to remember,” with its “gorgeous paved paths, stunning views and rolling country roads”, while noting occasional early-season wind and chill in late March.
Finishers receive commemorative medals connected magnetically across distances, tech shirts (guaranteed if registered by March 11), and age-group awards—first-place male/female finisher in the half earns \$100 and registration to next year free.
